               int y)

Sets the location of the playground (pixel coordinates of the upper left vertex).

Parameters:

x - the x-pixel-coordinate of the upper left vertex (positive to the right)

y - the y-pixel-coordinate of the upper left vertex (positive to the bottom)

useObstacle

public static void useObstacle(java.lang.String filename,
               int x,
               int y)

Defines the give images as an obstacle. It will be shown at the given position. More than one obstacle may be defined.

Parameters:

filename - the image file of the obstacle

x - the x-coordinate of the image center

y - the y-coordinate of the image center

useObstacle

public static void useObstacle(Obstacle obstacle)

Uses the given obstacle at the center of the playground. Mainly used for predefined obstacles.

Parameters:

obstacle - the obstacle to use.

showNavigationBar

public static void showNavigationBar(boolean doRun)

Shows the navigation bar of the GameGrid.

Parameters:

doRun - if true, runs the simulation immediatetly; otherwise the start button must be hit to run the simulation

showNavigationBar

public static void showNavigationBar()

Shows the navigation bar of the GameGrid and runs the simulation immediately.
